Key Advanced Geometry Worksheet 7.7: Squares Name:_______________________ Answer each question 1. A square has all the properties of a rhombus and rectangle. List the properties a square gets from both special parallelograms From Rhombus From Rectangle angles All sides are congruent All are I - perpendicular to are Diagonals each other which Diagonals bisect the angles they are drawn to - Diagonals be a right . need and all angles congruent angles but , congruent are . 2. Explain why this statement is false. “Every rhombus is a square.” has to have all side Because a square right angler - a angles square rhombus only needs to have all to sides congruent . all angles need to and congruent angles her to have all 3. Explain why this statement is false. “Every rectangle is a square.” has to have all side Because a be a right , but a rectangle only right . 4. ACGH is a square. Find the measure of each missing angle 6 M< KGO 1 2 3 m< 5 4 Mc ' 2=90 3=90 m< 4=45 Mc 5=45 m< ' a 6=90 For 5 – 7: Use the figure to the right 5. Using the distance formula, show the quadrilateral is a rhombus. dan Etch t.cm#=4.47 d. = = den dBc= FEET tetchy 447 It's a rhombus because all sides are I 4.47 = . = 4.47 6. Using the slope formula, show the shape is a rectangle.

What is the most specific way to classify quadrilateral ADCB? all creating right angles for corner angles . Square . the Determine if the state is ALWAYS, SOMETIMES, or NEVER true. 8. A parallelogram is a square 9. A square is a rhombus 10. Sometimes Always A rectangle is a parallelogram Always 11. A rhombus is a rectangle Sometimes 12. A rhombus is a square sometimes 13. A square is a rectangle Always Solve for x. The quadrilateral is a square. 14.
